Querying SQL Databases Using T-SQL

About this course

This course will provide you with the basic knowledge and skills to create queries using Transact-SQL. It will teach you how to select, filter and sort data from multiple tables and how to use views and stored procedures.

Audience profile

IT Professionals who will be writing queries for use with Microsoft SQL Server 2005, 2008, 2012, 2014 and 2016. Non-technical ‘power users’ will also benefit from the course if they are comfortable using sophisticated software tools like SQL Server Management Studio.

The course is aimed at both non-technical ‘power users’ and IT Professionals who will be writing queries for use with Microsoft SQL Server.

Lab :

  • Basic sorting
  • Sorting on expressions
  • Unique rows
  • Limiting results

Module 5: Grouping and Aggregating data

  • Single aggregates
  • GROUP BY
  • HAVING

Module 6: Using multiple tables

This module describes how to use JOIN clauses to retrieve data from multiple tables. It also covers the UNION, INTERSECT and EXCEPT keywords
